Description

Die Erfindung betrifft ein Kugelgelenk mit einem Gehäuse, einem Kugelzapfen und einem Dichtungsbalg, der an dem Gehäuse und dem Kugelzapfen anliegt, um zwischen diesen abzudichten.The invention relates to a ball joint with a housing, a ball stud and a sealing bellows attached to the housing and the ball stud to seal between them.

Nach dem Stand der Technik wird der Dichtungsbalg zapfenseitig in eine Nut eingelegt und mittels eines Spannrings befestigt und gehalten. Die hierfür erforderliche Zapfennut wurde bisher durch einen separaten Arbeitsgang hergestellt, beispielsweise durch Zerspanen, Rollieren oder ähnliches.According to the prior art, the sealing bellows pin side into a groove inserted and fastened and held by means of a clamping ring. The required for this Pin groove was previously produced by a separate operation, for example, by machining, rolling or the like.

Die Aufgabe der Erfindung besteht darin, ein Kugelgelenk der eingangs genannten Art dahingehend weiterzubilden, daß sich geringere Herstellungskosten und eine verbesserte Abdichtung ergeben.The object of the invention is a ball joint of the above educate mentioned type to the effect that lower production costs and give an improved seal.

Zu diesem Zweck ist erfindungsgemäß vorgesehen, daß der Kugelzapfen eine Haltefläche aufweist, an der eine Dichtungsfläche des Dichtungsbalgs anliegt, und daß die Dichtungsfläche im unverformten Zustand, betrachtet entlang der Längsachse des Kugelzapfens, länger ist als die Haltefläche. Die Erfindung beruht auf dem Grundgedanken, die erforderliche Vorspannung zwischen dem Dichtungsbalg und dem Kugelzapfen dadurch zu erzeugen, daß die Dichtungsfläche des Dichtungsbalgs bei der Montage des Kugelzapfens an seinem späteren Bestimmungsort in axialer Richtung zusammengedrückt wird. Der Begriff "unverformter Zustand" bezieht sich dabei auf den Ruhezustand vor der Montage im Fahrzeug. Es ist erfindungsgemäß nicht unbedingt ein Spannring erforderlich, der den Dichtungsbalg auf dem Kugelzapfen festspannt. Die Kugelzapfennut, die bisher aufwendig hergestellt werden mußte, kann auch eingespart werden. Weiterhin ergibt sich ein vereinfachter Montageprozeß, da der Dichtungsbalg nicht mehr definiert in der Nut im Zapfen positioniert werden muß, sondern lediglich auf die Haltefläche aufgeschoben werden muß.For this purpose, the invention provides that the ball pin a Has holding surface on which abuts a sealing surface of the sealing bellows, and that the sealing surface in the undeformed state, viewed along the longitudinal axis of the ball stud, is longer than the holding surface. The invention is based on the basic idea, the required preload between the sealing bellows and to produce the ball stud characterized in that the sealing surface of the Sealing bellows during assembly of the ball stud at its later destination is compressed in the axial direction. The term "undeformed Condition "refers to the idle state before mounting in the vehicle. It is inventively not necessarily a clamping ring required, the Tightly clamp the sealing bellows on the ball stud. The Kugelzapfennut, the previously could be made consuming, can also be saved. Farther results in a simplified assembly process, since the sealing bellows no longer defined in the groove must be positioned in the pin, but only on the Holding surface must be postponed.

Gemäß der bevorzugten Ausführungsform der Erfindung ist vorgesehen, daß die Haltefläche und die Dichtungsfläche zylindrisch sind. Eine zylindrische Haltefläche läßt sich mit geringem Aufwand herstellen.According to the preferred embodiment of the invention it is provided that the holding surface and the sealing surface are cylindrical. A cylindrical holding surface can be produced with little effort.

Vorzugsweise ist vorgesehen, daß sich an die Zapfen-Haltefläche auf ihrer vom Gehäuse abgewandten Seite eine Anlagefläche für ein Bauteil anschließt, an dem der Kugelzapfen angebracht werden kann. Auf diese Weise wird bei der Montage eine zusätzliche definierte axiale Vorspannung des Dichtungsbalgs auf dem Kugelzapfen erreicht, da die Endposition des Zapfens am Bauteil durch die Anlagefläche genau definiert ist. Hierdurch wird zusätzlich eine Dichtwirkung in axialer Richtung erzielt, die eine Verbesserung gegenüber den herkömmlichen Radialnutabdichtungen darstellt.It is preferably provided that on the pin-holding surface on her From the housing side facing away from a contact surface for a component connects to the ball stud can be attached. This way, at the Mounting an additional defined axial preload of the sealing bellows reaches the ball stud, since the end position of the pin on the component through the Investment surface is precisely defined. As a result, in addition, a sealing effect in achieved in the axial direction, which is an improvement over the conventional Radialnutabdichtungen represents.

Es kann vorgesehen sein, daß der Dichtungsbalg mit einem Metallring versehen ist, der die Dichtungsfläche gegen die Haltefläche beaufschlagt. Auf diese Weise läßt sich die radiale Vorspannung variieren.It can be provided that the sealing bellows provided with a metal ring is, which acts on the sealing surface against the support surface. To this Way, the radial bias can be varied.

Gemäß der bevorzugten Ausführungsform der Erfindung ist der Dichtungsbalg so bemessen, daß er nicht von der Haltefläche abrutschen kann, wenn das Kugelgelenk nicht an einem Bauteil angebracht ist. Dies gewährleistet, daß sich die Dichtungsfläche des Dichtungsbalgs vor der Montage des Kugelzapfens korrekt angeordnet und geführt auf der Haltefläche des Kugelzapfens befindet.According to the preferred embodiment of the invention, the sealing bellows so dimensioned that he can not slip off the support surface when the ball joint not attached to a component. This ensures that the Sealing surface of the sealing bellows before mounting the ball stud correctly arranged and guided on the holding surface of the ball stud is located.
